POLAR “WANDERING” CURVES We have learned that rock samples containing magnetic minerals (commonly magnetite) provide information (direction and inclination) on where they were formed relative to the north magnetic pole. WebThis paleomagnetic work of the 1950s was the first new evidence in favor of continental drift, and it led a number of geologists to start thinking that the idea might have some …

Webcontinental drift . However, we now know that it is not just the continents that move, so a more correct term is plate tectonics . We can credit Alfred Wegener (Figure 4.1.1) as the originator of this idea. Figure 4.1.1 Prof. Dr. Alfred Wegener, ca. 1924-1930 (Public domain, via Wikimedia Commons). WebThe revival of interest in continental drift by the interpretation of paleomagnetic data in terms of large-scale displacement also revived interest in paleoclimates.

Initially, they interpreted their results as “a slow ... WebIn the 1950s, paleomagnetic evidence supporting continental drift became available. When rock is in a molten state, the magnetic particles it contains are free to move around, and they orient themselves toward the Earth's magnetic poles. Once the rock cools and hardens, the orientation of the individual magnetic particles becomes fixed.
